If one absolutely insists on branch circuit protection at the AC receptacle, MOV shunt mode from line-to-neutral, rather than line-to-ground, is generally acceptable. These are referred to as "single-mode" surge protection devices (SPD). By contrast, most receptacle and power strip SPDs utilize the so-called "3-mode" MOV shunting and can produce the disastrous results that Joe and K9YC have described.
